AUTOMATIC ELECTRIC TIME-SWITCH,

Specification of Letters Patent.

I Patented Feb. 5, 1907.

Application filed Time 8,1906. Serial NO BZCLbSQ- Tona whom) it may concern: V 130 it known thatxI, LESLIE C. DORLA'NDQ a citizen of the United States, residing at. Poughkee. sic, the county of Dutchess and ew York; have invented new and useful Improvements in Automatic Electric Timeesw'itches, of which the following is a specification. Y .Myrinvention is an improved automatic electric time-switch apparatus adapted at anypredetermined time to release thesprin actuated lever of an electric switch-to enab e thc-. s'aid lever to move ;totheposition required to break the circuit or circuits con-'- trdlled by'thesaid switch to put out the lights pldiscontinue the operation of other translatingdevice's in such circuit or circuits; and-it consists in the construction, combination, and arrangement of devices hereinafterde- *scnbedand claimed.

In the accompanying drawings, Figure '1 is an elevation of electric time-switch appara- 'tus embodying my invention, the casing in which the same is inclosed being shown in section. Fig. 2 is a top plan view of the same, theflever of the switch and the casing beingshown in section. Fig. 3 is a detail perspec- .tiveview of the trip arm of the alarm-mechanism-winding arbor of the clock.

The inclosing' casing 1 (here shownfis provided at the back'2 with hangers-3; whereby it may be secured on a wall. It also has a door 4, hinged at 5 and provided with a fastening'device 6.

,In the casing and secured to the rear wall thereof is a switch 7, here shown as a knifeswitch, provided with a spring'8 to throw the switch-lever 9 to open position. The arm 10 4 of the switch-lever operates in a slot 1 1 in the top of the casing. To the rear wall of the casing-is secured the inner end of a detent, which is a spring-arm 12 that bears against. :the arm 10 and is bent at a suitable point to provide a shoulder 13, which engages the said arm when the switch-lever .is closed to hold such switch-lever in closed position.

An alarm-clock 14 of usual construction is secured to and carried by the door of the easin'g, the face of the clock showing through an opening 15 in the door. The major portion of the cock-case projects from the inner side of the door and extends into the casing 1 when the door is closed. To the winding arbor of the alarm mechanism'offthe clock is attached a 'trip-arm lfir: Such trip-arm is .turned in one direction to wind the-alarm mechanism and remains'in the position indicated in fulllines in Fig. 2 until-the alarm mechanism is sprung by -the clock'at'the predetermine'dtime and when the said trip-arm moves to the 'position shown indotted lines in such When the door of'the casing is closed, the

free end of the detent 12 the path of the said trip-arm, and hence. the movement of- I such trip-arm when the. alarm mechanism is sprung causes thedetent tobejdisengaged from the lever-arm ofthe switch; whereupon the spring Smoves thef said lever to. open position. L o

From the foregoingrdes'cript ion; taken in connectionwiththe accompanymgdrawings, the construction and operation of the inven' t1on will be readily understood without re-l quiring a more extended e lanation.

Various changes in the orm,'proportion, and the minor details ofr eonstruetion may be resorted to without departing from the principle or sacrificing anyof the advantages of tll1e .invention as. defined by the appended c aim.

Having thus described my-invention, what I claim as new, and desire to secure by Letters Patent, is

The hereindescribed automatic timeswitch apparatus comprising the casing havlng the movable door and rovided with the slot in one side, .an alarm-c ock having a triparm attached to the winding-arbor of the I alarm mechanism, a switehsecnred inthe cas ing and having 7 a 1 switch-lever extending
